IMPROVEMENT IN CLOTHES-POUNDERS.

Specification forming part of Letters Patent No. 215,176, (lated May 6, 1879; application filed January 11, 1879.

To all whom t may concern:

Be it known that I, DANIEL SQUIER, of Bat tle Creek, in the county of Calhoun and State of Michi gan, have invented a new and valuable Improvement in Washing-Machines; and I do hereby declare that thefollowin g is a full, clear, and exact description of the construction and operation of the saine, reference being had to the annexed drawing, making a part of this specification, and to the letters and gures of reference marked thereon.

The drawing is a representation of a longitudinal section, taken centrally, of m y improved pressure washing-machine.

The nature of the invention consists in the Yconstruction and novel arrangement of a clothes-pounder, having a hollow handle extending downward within a plunger and threaded at its lower end, in combination with an inner reciprocating plunger and a threaded cap, having a disk-valve working on a pin fixed to a cross-bar under the cap. '1

It also consists in a cylinder clothes-pounder having a perforated hollow handle, valved at its lower end, a reciprocating inner cylinder tting neatly within the outer plunger, kept in position by a spring, and having communieating openings at its top, whereby an enlarged air-chamber is formed, which is c'ontracted by the strokeforcing the inner cylinder up into the outer one, as hereinafter shown and described.

In the accompanying drawing, the letter A designates the main cylinder of the plunger, having a flaring flange, b, at its mouth. C represents the hollow handle of the plunger, having air-holes a in its outer end, and extending into the plunger-cylinder A about half the distance between its top c and its flange b. The lower end of this hollow handle is externally threaded.

D indicates the extension or inner movable. cylinder, which is formed to fit neatly but not tightly withinV the main plunger-cylinder, which therefore acts as a guide and bearing for the inner cylinder in its movements. In its top are made air-holes d, and a central aperture, e, through which passes the end of the handle C, which is within the plunger, and serves as a central guide to keep the inner cylinder true.

A screw-cap, E, having a valve, g, is turned upon the threaded end of the handle, and secures the inner cylinder in place.

The valve g consists of a concave plate or disk having a central perforation, whereby it is centered upon a pin, k, which extends into the cap from a cross-bar, l, under the same, connected to each side thereof, and forming a guard to prevent any obstruction from interfering with the free action of the valve. It also serves as a handle to screw the cap on its seat.

Between the tops of the two cylinders is arranged a spiral spring, s, which keeps the inner cylinder extended beyond the lower margin or flange of the outer cylinder when the machine is not pressed in contact with any object which would overcome the power of the spring.

rlhis machine operates as follows: Being pressed down on the articles in the wash-tub, the outer plunger-cylinder is forced down over the inner one, and the air-space therefore contracted, and the disk-valve at the lower end of the hollow handle being closed, the air is ejected from under the bottom of the inner cylinder, and acts upon the articles inf the tub. W'hen the plunger is raised the spring keeps the inner cylinder down, and the enlarged airspace thus formed is filled by thepassage ofthe air through the perforations in the handle end, the disk-valve in the lower end of the handle being opened. A

I am aware that it is not new to arrange a reciprocating cone below the main `conical plunger, and I do not claim such devices.

What I claim, and desire to secure by Letters Patent, is-

1. The handle of a washing plunger extended downward within the plunger and threaded, in combination with an inner reciprocating plunger and a threaded cap, having a disk-valve working on a pin fixed to the cross-bar under said cup, substantially as by the stroke forcing the inner cylinder up specified. into the outer one, as specified.

2. A cylinder clothes-ponmler having :i per- In testimony that l claim the above I have forated hollow handle, C, valved at its lower hereunto subscribed my name in the presence end, and an inner extension-cylinder, D, tof two Witnesses.
